Take a bunch of common parts, and create the hottest set of wheels around.
I got almost everything here for cheap or free, or from a swapmeet.
Say goodbye to making gliding motions in order to skate - now you can stand still and watch the scenery pass you by!

Step 1: Angle Grinder
I got this one at a swapmeet for $9.
Take off the guard plate (if yours has one) with a screwdriver.
Step 2: Power Source
You can run power tools on dc power
Along those lines, I threw together five 12V batteries. More batteries = more power.
Test to make sure they're all roughly the same voltage, or one will drain the others.
Together, my pack measured 60V.
the wire connections to make them fast-disconnecting, and less prone to spark or come off. Covering them with tape might have worked just as well.
Step 3: Connect the Grinder to power
Remember to insulate with some electrical tape or something.
Sparks and shorts are exciting, but will burn your carpet, and make your batteries sad.
Step 4: Attach a wire brush
This cost me around $4 at the local hardware store.
Spin it on finger-tight - the angle grinder will self-tighten as it spins.
Step 5: Tape the On Switch "on"
So that when you plug in the angle grinder, it goes. I mean GOES. Full-speed.
It's probably a good idea to put a switch somewhere, so you can turn this beast-machine off.
In this version, I just put trust in my sense of balance and lifted my foot off the ground while flailing to find a power cable to rip out. This clearly stood out as the better of the two options.
Step 6: Make your battery pack portable
I got this bag for free - throw the batteries in anything you can carry whilst 'blading.
I considered making a battery-belt, for more even weight distribution. The bag was definitely less comfortable, so I went with it.
I taped the batteries together before throwing them in the bag, to keep them together and prevent shorts.
Step 7: Don Gear
Get set -
Step 8: Attach Skates & Grinder
Duct Tape - $1.
Do whatever to make the grinder attached sturdily to your leg.
Make sure the wheel is spinning in the right direction.
Step 9: Go!
These skates create plumes of concrete dust smoke behind you - awesome!
I wonder if I could win at the Seattle Power Tool Drag Races
